Questions:
- What do you know about the speed of the wave in a nonchanging medium? (review question)
- How do you know the speed is constant? (review question)
- What are your independent and dependent variables?
- For a constant velocity wave, how is frequency related to wavelength?
- Explain how your data shows that frequency and wavelength are inversely proportional.
- Does the slope have any meaning? Do the units look familiar?
- How can we verify that the slope is the speed?
- How are the standing waves formed?
- How do the reflected and outgoing wave interact?
- Which principle are we using?
- Explain the superposition principle.
- Was a standing wave formed at every disturbance frequency of the wave?
- What happened when the disturbance frequency did not form a standing wave? (This is a nice bridge into a discussion of resonance.)
